JOHN KREHBIEL, OF DETROIT, MICHIGAN.

CAPSULE-MACHINE.

BPECIFICATION forming part of Letters Patent No, 315,417, dated April 7, 1885.

Application filed March 26, 1884. (No model.)

To aZZ whom, it may concern:

Be it known that I, JOHN KREHBIEL, of Detroit, in the county of Wayne and State of Michigan, haveinvented new and useful Improvements in Bing-Cutters for Cutting Capsules; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a certain new and useful device or hand-tool adapted to be used for cutting off capsules to a uniform and desired length upon the mold-pins upon which such capsules are formed; and the invention consists in the peculiar construction of the device, its parts, their combination and operation, as more fully hereinafter described.

In the accompanying drawing, which shows a perspective view of the entire device, A represents a circular plate, from the upper face of which, at equal distances apart, project the mold-pins a, which are set in said circular plate A. B is another circular plate,of the same size as the plate A, and this plateB is provided with a series of holes, I), which, when the two plates A and B are coincident, are coincident with the projecting mold-pins over which the plate B is slipped. Resting upon the upper side of this plate B, coincident with the holes therein, are the ring-cutters 0, formed of thin pieces of steel sharpened upon the inner edge of the ring, and these ring-cutters are held in place by means of the thin metallic plates D, which in turn are secured to the outer side of the circular plate B by means of setscrews c, and by slightly loosening one of the set-screws the ring-cutters may be removed for sharpening or other purposes, and easily replaced and secured.

E are studs projecting from the upper face of the plate A, or from the lower face of the plate B, asmay be desired, and the ends of these studs are threaded to engage with such plates to adjust the distance between the two when the cutters are in use, such distance determining the length of the capsule.

F is a bar rigidly secured to the plate B centrally, and through this bar and the plate B, at each end of said bar, is formed a circular hole, 61, through which holes (1 pass the is in operation into coincident recesses e in the upper face of the plate A. The holes through which the shafts pass are of sufficient size to allow a cam or eccentric face, f, to be two rods or shafts G, the lower ends of such shafts being stepped when the cutting device built or formed upon the shaft G, and the upper end of each of these shafts is provided with a crank, H, both such cranks being connected together by a bar or rod, I, which is provided with handles J, by means of which a simul-,

taneous movement is given to both shafts.

In practice, the length of the capsules to be i out upon the molds a having been determined,

and the studs or stops E properly regulated, i the plate B, carrying the cutters, is placed over the plate A, the mold-pins passing up .through the ring-cutters, and the lower ends of the shafts G engaging with the recesses e in the plate A. Now, the operator with each hand grasps the handles J, and gives a turn of the cranks, whereby an eccentric movement is'given to the plate B, carrying the cutters,

by which the ringcutters are brought successively into contact all around the moldpins, thereby cutting off the capsules to the I desired length. K is a lever pivotally se cured at one end, and adapted by its movement to slightly change the position of the upper plate, B, by so much as the thickness of the cams or eccentric beyond the common I axis of the shaft.

A substantial equivalent for the plate carrying the cutters, the eccentric-shafts, andthe plate carrying the capsule mold-pins and provided with bearings for the shaft is shown l and removableand adjustabl y secured in place by thin plates bearing on two or more cutters, and set-screws for securing said'plates, substantially as described.

2. In a hand-tool for cutting off capsules,

the plate B, carrying the capsule-cutters, and b, ring-cutters 0, held in place by the plates provided with shafts constructed to give said D and set-screws c, the shafts G, provided with plate an eccentric motion, in combinationwith eccentrics f, the cranks H, coupling-bars I,

a plate carrying the mold-pins, and provided and handles J, the parts being constructed, :5 5 With bearings for the shafts, and stops, as the combined, and operating substantially as and studs E, arranged between the plates to regufor the purposes specified.

late the len th of the capsules substantially 1 as describea: JOHN KREHBIEL.

8. A hand-tool for cutting capsules, consist- Witnesses: IO ing of the following elements: a circular plate, CHARLES J. HUNT,

B, provided with one or more series of holes, H. S. SPRAGUE.
